The new cavern mines are cool indeed, but somehow it's a bit hard to travel due to having cave walls formed as a wall and will need to find a way to get out of it.

It is possible to get up top but you need to mine holes in the wall often to do it. So you can mine your way up. There are usually spots where you can just jump if you have the right layout, but they can require some searching. There are lots of corridors connecting the various wider caverns though. From the top of the caves you can't always see where the caverns are because they have roofs that are fadey-foamed. So from above it just looks dark. (not all cave chambers have roofs.. just some)
